Let's do the math here.
Approximately five months ago, I was getting maybe two hour stretches of sleep at night. I felt soooo tired in the morning, and longed for naps and better sleep. All I wanted was 3-4 hour chunks of rest! Really!
Approximately two months ago, I started getting 3 hour stretches. But was still soooo tired in the mornings. I just needed a little more, like six hours at a stretch.
Now. I am getting six hour stretches. And a little bit after that. And I am still soooo tired in the mornings. I just need a little bit more, like nine hours at night.
Apparently my body is to sleep like a small child is to ice cream.
